About this tool

Rolls virtual dice - from a standard d6 up to d100 and beyond - in any combination and quantity, useful for tabletop games, random decision-making, or anytime you need a physical dice roll simulated digitally.

How to use this tool

  1. Choose dice notationSelect die type and quantity like `3d6` or `1d20`.
  2. Set optional modifiersAdd bonus/penalty values if your game system uses them.
  3. Roll diceGenerate random face values and total instantly.
  4. Log resultUse output for gameplay turns or probability experiments.

Dice notation explained

In tabletop games, 3d6 means roll three six-sided dice and add them; 2d6+3 means roll two d6 and add 3. Dungeons & Dragons uses a full set: d4, d6, d8, d10, d12 and d20, plus percentile dice (d100) in some rules.

Rolling two dice makes some totals more likely than others: with 2d6, 7 comes up most often (6 ways out of 36) and 2 or 12 least often (1 way each). A single die has an equal chance for every face.

Key features

  • Replaces physical dice for remote or quick sessions.
  • Supports many RPG and tabletop dice formats.
  • Instant totals reduce manual arithmetic errors.
  • Useful for both games and random decision tools.

Common uses

  • Running DnD and tabletop RPG checks online.
  • Simulating random outcomes in classrooms.
  • Settling simple random choices quickly.
  • Testing probability scenarios with repeated rolls.

Tips for better results

  • Use standard notation for faster repeat rolls.
  • Keep roll history visible during competitive play.
  • Agree rules for rerolls/modifiers before game starts.
  • Use larger test batches when studying probabilities.

Mistakes to avoid

  • Applying modifiers twice in manual scoring.
  • Using wrong die type for a rule check.
  • Ignoring agreed game constraints on rerolls.
  • Treating short roll streaks as true long-term odds.

Frequently asked questions

Common tabletop gaming dice types from d4 up through d100, covering the standard sets used in tabletop RPGs and board games.

Yes - specify both the number of dice and the die type to roll multiple dice together in one action, with the total shown alongside individual results.

Yes - each roll uses fresh randomization, just like a physical dice roll, rather than following any predictable pattern.

The first number is how many dice, the d-number is the sides on each die, and the modifier is added at the end. 2d6+3 means roll two six-sided dice and add 3, for a result from 5 to 15.

The standard set is d4, d6, d8, d10, d12, d20 and a percentile d100. The d20 decides most attacks and checks; the others roll damage and effects.

There are six ways to roll a 7 with two d6 but only one way to roll a 2 or a 12. Adding dice together makes middle results more likely, which is why board games built around 2d6 feel predictable.
